The Metrop MR2 is a very high concentrated liquid flower fertilizer with NPK 10-20-40.
Maximum use is 100ml in a 100 liter water tank.
That means you don't have to carry large bottles of fertilizers anymore. A 1 litre flower fertilizer from Metrop is the same as a 5 to 10 litre from most other brands.
In the Metrop MR2 flower fertilizer, the NPK and micro-element balance is specially formulated to produce the highest possible flower buds from the plant.
The most Potash in a plant is in the buds.
The more Potash gets fed to fruit or flower buds, the fatter the fruit of flower buds will become!
That is the basic rule, but for the largest volume increase, you need twice the potash than phosphorus!
If the PK level is the same or almost the same, the flower buds will not reach maximum size.
That is why Metrop MR2 has an NPK value of 10-20-40. A flower fertilizer and PK booster in one that has been adapted for optimal flowering explosion.
To get big buds many cultivators use bloom boosters to stimulate the plant. However, a bloom booster cannot stimulate the flower buds to the maximum without an NPK fertilizer high in potash.
Also the MR2 assures the availability of sufficient magnesium for optimal chlorophyll and protein synthesis and contains micro nutrients required for full fruit bloom.
The raw materials of Metrop MR2 flower fertilizer is of very high purity, which makes it possible to achieve a high NPK proportion that stay stable.
The quality of the raw materials ensures that it will never clog the vat or irrigation system. Once prepared with water, the EC will remain stable.
The micro elements are also added to a higher and purer degree, so that the plants have a faster and better photosynthesis, which is beneficial for the quality of the end product.
Metrop MR2 does not contain any harmful colouring and is not diluted with water, it consists only of the purest raw materials. The Metrop MR2 is biological degradeble.
When do you start with flowering fertilizer?
It make no sense to start with big buds nutrients if there are no flower buds. Often indoor growers start giving the plants flower nutrients right when they put the day/night cyclus at 12/12 hours in the flower stage. The plant is not ready yet to receive high amount of Potash to make the buds big because there are any buds to make big.
How this work you can read this blog about Phyto hormones.
With most plants we see the flowering in week 4. Ones the flower buds are there as big as your finger, it make sense to start fertilize with big buds nutrients.
Why would you buy fertilizers that are like water if you can buy real concentrated liquid fertilizers?
